// Register a new V8 extension with the specified JavaScript extension code and
// handler. Functions implemented by the handler are prototyped using the
// keyword 'native'. The calling of a native function is restricted to the scope
// in which the prototype of the native function is defined. This function may
// only be called on the render process main thread.
//
// Example JavaScript extension code:
// <pre>
// // create the 'example' global object if it doesn't already exist.
// if (!example)
// example = {};
// // create the 'example.test' global object if it doesn't already exist.
// if (!example.test)
// example.test = {};
// (function() {
// // Define the function 'example.test.myfunction'.
// example.test.myfunction = function() {
// // Call CefV8Handler::Execute() with the function name 'MyFunction'
// // and no arguments.
// native function MyFunction();
// return MyFunction();
// };
// // Define the getter function for parameter 'example.test.myparam'.
// example.test.__defineGetter__('myparam', function() {
// // Call CefV8Handler::Execute() with the function name 'GetMyParam'
// // and no arguments.
// native function GetMyParam();
// return GetMyParam();
// });
// // Define the setter function for parameter 'example.test.myparam'.
// example.test.__defineSetter__('myparam', function(b) {
// // Call CefV8Handler::Execute() with the function name 'SetMyParam'
// // and a single argument.
// native function SetMyParam();
// if(b) SetMyParam(b);
// });
//
// // Extension definitions can also contain normal JavaScript variables
// // and functions.
// var myint = 0;
// example.test.increment = function() {
// myint += 1;
// return myint;
// };
// })();
// </pre>
// Example usage in the page:
// <pre>
// // Call the function.
// example.test.myfunction();
// // Set the parameter.
// example.test.myparam = value;
// // Get the parameter.
// value = example.test.myparam;
// // Call another function.
// example.test.increment();
